Answer:
a
The power is =12.54 KW
b
Now the above solution of power requirement is valid for an adiabatic process which is not the case in reality. In reality we will have losses, both mechanical and frictional. So now the question is will more power be required or less
Now since the above Solution of adiabatic case was ideal didn't take care of any heat losses or frictional losses, additional energy will be required to overcome this losses and hence, in total we will actually more power than that calculated in part (A)
